Basket trial, as an innovative clinical trial design concept, marks the transformation of medical research from the traditional large-scale and single-disease treatment to the precise and individualized treatment. By gradually incorporating the Bayesian method during development, the trial design becomes more scientific and reasonable and increases its efficiency. The fundamental principle of the Bayesian method is the utilization of prior knowledge in conjunction with new observational data to dynamically update the posterior probability. This flexibility enhances the basket trial's capacity to effectively adapt to variations during the research process. Consequently, it enables researchers to dynamically adjust research strategies based on accumulated data and improve the predictive accuracy regarding treatment responses. In addition, the design concept of the basket trial aligns with the traditional Chinese medicine(TCM) principle of "homotherapy for heteropathy". The principle of "homotherapy for heteropathy" emphasizes that under certain conditions, different diseases may have the same treatment. Similarly, basket trials allow using a uniform trial design across multiple diseases, offering enhanced operational and significant practical value in the realm of TCM, particularly within the context of syndrome-based disease research. By introducing basket trials, the design of TCM clinical studies will be more scientific and yield higher-quality evidence. This study systematically categorized various Bayesian methods and models utilized in basket trials, evaluated their strengths and weaknesses, and identified their appropriate application contexts, so as to offer a practical guide for designing basket trials in the realm of TCM.

Aim To express and purify recombinant hCGH-CTP fusion protein in high-density suspension culture of Chinese hamster ovary cells (CHO-S), and to verify the lipid accumulation effect of rhCGH-CTP on 3T3-L1 mature adipocytes. Methods The recombinant protein expression vector (pcDNA3. 1-rhCGH-CTP) was constructed, achieved by fusing the human glycoprotein hormone beta 5/alpha 2 cDNA with CTP Linker. The expression plasmid was transiently transfected into the suspended CHO-S to express rhCGH-CTP protein and then purified, and the protein biological activity was verified. Intervention with 3T3-L1 mature adipocyte cells for 24 h was performed to detect the changes of intracellular triglyceride (TG) level. Results Western blot results showed that rhCGH-CTP protein was successfully expressed in CHO-S cells, and the yield was up to 715. 4 mg • L~ . The secreted protein was purified by AKTA pure system with higher purity that was up to 90% as identified by SDS-PAGE. In addition, the intracellular cAMP content of mature adipocytes with high expression of TSHR gene significantly increased after intervention with different concentrations of rhCGH-CTP protein by ELISA kit, indicating that rhCGH-CTP protein had biological activity. Oil red 0 staining showed that compared with the control group, the lipid content of mature adipocytes in the intervention groups with different concentrations of rhCGH-CTP protein significantly decreased (P < 0. 05) . Conclusions The rhCGH-CTP protein has been successfully expressed and purified with biological activity, and effectively reduce TG. This research provides an important theoretical basis for further revealing the physiological role of CGH protein and its potential application in clinical practice.

International guidelines regarding the role of intravenous immunoglobulin (IVIG) in the management of Rh- and ABO-mediated haemolytic disease of the newborn was drafted by an international panel of experts in the fields of hematology, neonatology, and blood transfusion and was published in British Journal of Haematology on March 16, 2022. The guidelines summarize the evidence-based practice of IVIG in Rh- and ABO-mediated haemolytic disease of the newborn and propose related recommendations. The guidelines recommend that IVIG should not be applied as a routine treatment regimen for Rh- and ABO-mediated haemolytic disease of the newborn in order to reduce exchange transfusion (ET), and the best time to apply IVIG remains unclear in the situations where hyperbilirubinaemia is severe (approaching or exceeding the ET threshold) or ET cannot be implemented. These guidelines are formulated with rigorous methods, but with the lower quality of evidence.

OBJECTIVE: To observe the effect of blistering moxibustion on the expression levels of 5-hydroxytyptamine (5-HT) and its receptors of the colon tissue in the mice with visceral hypersensitivity of irritable bowel syndrome (IBS), so as to explore the effect mechanism of blistering moxibustion in treatment of IBS. METHODS: Forty SPF-grade newborn Kunming mice were randomly divided into a normal group, a model group, an antagonist group and a blistering moxibustion group, 10 mice in each one. Before modeling, the injection with 0.2 mL parachlorophenylalanine (PCPA) was given on the lateral ventricle in the antagonist group. The endorectal glacial acetic acid stimulation combined with tail clipping was used to prepare the model of visceral hypersensitivity of IBS in the model group, the antagonist group and the blistering moxibustion group. After modeling, in the blistering moxibustion group, the intervention with blistering moxibustion was exerted at "Zhongwan" (CV 12), "Tianshu" (ST 25) and "Zusanli" (ST 36), once herbal irritant plaster at each acupoint, for 2 h each time, once a week, consecutively for 3 weeks. Abdominal withdrawal reflex (AWR) score and electromyographic (EMG) amplitude of abdominal muscles were adopted to evaluate the visceral hypersensitivity. HE staining was applied to observe the morphological changes in colon tissue, and immunohistochemistry was to determine the expression levels of 5-HT and its receptors. RESULTS: Compared with the normal group, EMG amplitude of abdominal muscles was increased under 20, 40 mm Hg (1 mm Hg=0.133 kPa) in the model group (P<0.05), AWR scores and EMG amplitude of abdominal muscles under 60, 80 mm Hg were all increased in the model group (P<0.05). In comparison with the model group, EMG amplitude of abdominal muscles was reduced under 20 mm Hg in the blistering moxibustion group (P<0.05), AWR scores were increased under 40 mm Hg in both the blistering moxibustion group and the antagonist group (P<0.05); AWR scores and EMG amplitude of abdominal muscles under 60, 80 mm Hg were all reduced in both the blistering moxibustion group and the antagonist group (P<0.05). Compared with the normal group, in the model group, the mucosa was slightly disturbed, while, the moderate inflammatory cells were visible in the submucosa. In comparison with the model group, the inherent glands of mucosa were regular in shape and a small number of inflammatory cells were visible in both the blistering moxibustion group and the antagonist group. In comparison with the normal group, the average positive staining area percentage (APSAP) of 5-HT and 5-HT₃R of the colon tissue was increased, while, APSAP of 5-HT₄R was reduced in the model group (P<0.05). Compared with the model group, APSAP of 5-HT and 5-HT₃R was reduced in both the blistering moxibustion group and the antagonist group (P<0.05). CONCLUSION Blistering moxibustion can relieve the visceral hypersensitivity of the mice with visceral hypersensitive IBS and the underlying mechanism is related to the regulation of the gut-brain axis mediated by 5-HT signaling pathway.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Lancang-Mekong Cooperation is a new type of subregional cooperation mechanism initiated and built by China and other five countries of the Lancang-Mekong subregion, namely Laos, Myanmar, Thailand, Cambodia, and Vietnam. Countries in the Lancang-Mekong subregion are geographically and culturally connected, and they have nurtured their unique traditional medicine. By combing the history of traditional medicine exchanges between China and other Lancang-Mekong countries and their progress of modern research, this paper summarized the challenges and opportunities of traditional medicine cooperation in the Lancang-Mekong subregion. It has been found that many regional cooperation mechanisms coexist for a long time in the Lancang-Mekong subregion and the medicinal resources are abundant. However, the degree of their development and utilization varies, and modern scientific research is insufficient. Lancang-Mekong Cooperation has provided a strong support for integrating the advantageous resources in Lancang-Mekong subregion countries and making progress together. Focusing on the development and protection of medicinal resources, this paper puts forward a new path of cooperation in the intellectual property rights and characteristic seed resource protection, the compilation of universal herbal pharmacopoeia in various countries, the research and development of public health products, and the construction of traditional herbal industry bases, thus enabling the traditional medicine to better protect the public health and building a human health community.
